A control apparatus for controlling multiple power loads in a vehicle includes a circuit for detecting a current abnormality of a power element and a circuit for monitoring a temperature abnormality in a locality of the power element. Circuits are also provided continuing or shutting down the power element based on information concerning the above stated current and/or temperature abnormalities, with a timing which is established according to a substantially constant period or a time interval which is stored in advance in a memory element.

1. An apparatus with an over-current shutdown means and an over-temperature shutdown means, comprising:a power element for maintaining operating continuity or causing a shutdown of a power supply to a load which is mounted on a vehicle; a current detection means for detecting a value of a current which flows in said power element; a current-voltage converting means for converting said detected current value to a voltage signal; a temperature detection means for detecting a quantity of heat generated by said power element and for varying one of said voltage signal and said current value in response to said quantity of heat generated by said power element; a latch means for maintaining a predetermined condition of said power element in response to an output from said current detection means and said temperature detection means; a return pulse generator for generating a return pulse so as to return said latch means to an initial condition; and a continuity and shutdown control means for maintaining said operating continuity or causing a shutdown of said power element in response to said output of said latch means.
